Based on the Landsat series images, an interpretative identifier for identifying the coastline was proposed to assess the hydrodynamic changes caused by the coastline change and was applied to a typical case of the Bohai Sea (BHS), China. We combined a grid-based coastline position with an adjoint data assimilation method to seamlessly map the distribution of the amplitude, phase lag, and tidal current of the M2 tidal constituent along the BHS\u2019s coast from 1985 to 2018. Our findings reveal that the coastline change at long time scales dominated reclamation, and around 72.9% of the coastline of the BHS mapped in 2018 had seaward movement compared with its position in 1985. From 1985 to 2018, the BHS volume decreased by 0.17%, the sea surface area decreased by 4.54%, and the kinetic energy increased by 2.53%. The change in the coastline increased the amplitude of the M2 tidal constituent in the Bohai Bay by 6\u201314 cm and increased the residual current in the eastern coast of the Liaodong Bay by up to 0.07 (0.01) m\/s.<\/jats:p>","DOI":"10.3390\/rs14215549","type":"journal-article","created":{"date-parts":[[2022,11,4]],"date-time":"2022-11-04T04:00:51Z","timestamp":1667534451000},"page":"5549","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["The Temporal Evolution of Coastlines in the Bohai Sea and Its Impact on Hydrodynamics"],"prefix":"10.3390","volume":"14","author":[{"given":"Jingfang","family":"Lu","sequence":"first","affiliation":[{"name":"Frontier Science Center for Deep Ocean Multispheres and Earth System (FDOMES) and Physical Oceanography Laboratory, Ocean University of China, Qingdao 266100, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4227-7708","authenticated-orcid":false,"given":"Yibo","family":"Zhang","sequence":"additional","affiliation":[{"name":"Frontier Science Center for Deep Ocean Multispheres and Earth System (FDOMES) and Physical Oceanography Laboratory, Ocean University of China, Qingdao 266100, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7994-7579","authenticated-orcid":false,"given":"Xianqing","family":"Lv","sequence":"additional","affiliation":[{"name":"Frontier Science Center for Deep Ocean Multispheres and Earth System (FDOMES) and Physical Oceanography Laboratory, Ocean University of China, Qingdao 266100, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3364-6644","authenticated-orcid":false,"given":"Honghua","family":"Shi","sequence":"additional","affiliation":[{"name":"First Institute of Oceanography, Ministry of Natural Resources, Qingdao 266061, China"},{"name":"Pilot National Laboratory for Marine Science and Technology, Qingdao 266237, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"113293","DOI":"10.1016\/j.rse.2022.113293","article-title":"Assessing the accuracy of Sentinel-2 instantaneous subpixel shorelines using synchronous UAV ground truth surveys","volume":"282","author":"Pucino","year":"2022","journal-title":"Remote Sens.
